- Executive summary:
Determination of the boiling point of LUMULSE GMT-K according to OECD 103 resp. EU A.2
Findings and Results:
The boiling point was determined via DSC (differential scanning calorimetry).
Because of the specificity of the DSC 4000 (445 °C is the highest measure temperature); no complete Peak could be detected.
The test item showed possible signs of decomposition beginning at 328.46 °C (601.61 K) indicated by lowering of the baseline.
The followed detected endothermic event with a maximum of 429.26 °C (702.41 K) (highest value) can be interpret as the boiling point.
Therefore the boiling point of the test item under decomposition can be stated with 418.78 °C (691.93 K) under the given test conditions.
This value is the mean of two independent determinations.

Security Pre-test for the DSC instrument
The crucible was found visual changed after reaching a temperature of 450 °C. The top colour of the crucible was completely grey-brown coloured. Therefore, a second crucible with less test item was heated to 450 °C. This crucible was just brown at the perforation. The weight was recorded with 46.06 mg for the first crucible and 49.41 mg for the second.
Calibration
After calibration with indium and zinc the measurement of indium yielded the following values:

Interpretation of the measurements
In every measurement, a lowered baseline was detected, which could be a sign for decomposition of the test item. The beginning of decomposition was evaluated with the event marker function. Based on the observations of the pre-test and the visually change of the test item inside the crucible, the endotherm peak can be interpreted as boiling. As the left tangent of the left peak was detected the onset equates the event marker set there. As where the left half tangent of the peak meets the baseline correspond to intercept point the temperature of the onset value is calculable. The beginning and the peak maximum were evaluated with event marker, too.

DISCUSSION
The boiling point was determined via DSC (differential scanning calorimetry).
Because of the specificity of the DSC 4000 (445°C is the highest measure temperature); no complete Peak could be detected.
The test item showed possible signs of decomposition beginning at 328.46 °C (601.61 K) indicated by lowering of the baseline.
The followed detected endothermic event with a maximum of 429.26 °C (702.41 K) (highest value) can be interpret as the boiling point.
Therefore the boiling point of the test item under decomposition can be stated with 418.78 °C (691.93 K) under the given test conditions.
This value is the mean of two independent determinations.
No observations were made which might cause doubts on the validity of the study outcome.
Therefore, the result of the study is considered valid.
